如何修改Python的SenGen函数生成指定格式的飞机服务描述语句？

First, let’s fix the core issues with your original code: the loop logic was misaligned between aircraft types and their services, and there was no way to inject those descriptive context phrases you want. Here’s a revised approach that addresses both and produces the structured sentences you’re looking for:

Step 1: Add Context Phrases #

Create a dictionary to map each aircraft type to its specific descriptive clause—this makes it easy to update or expand later:

# Define context phrases for each aircraft type
aircraft_context = {
    'Cargo Aircraft': 'that handle international and domestic freight',
    'International Aircraft': 'that operate from various airports of India',
    'Domestic Aircraft': 'which run within India'
}

Step 2: Rewrite the SenGen Function #

We’ll restructure the function to properly link aircraft types to their services, inject the context phrase, and format the service list cleanly:

def SenGen(services, aircraft_types):
    # Iterate over each aircraft type in your AirCrafts dict
    for aircraft_type, _ in aircraft_types.items():
        # Fetch the corresponding services for this aircraft type
        aircraft_services = services.get(aircraft_type, [])
        
        # Handle case where no services exist
        if not aircraft_services:
            print(f"{aircraft_type} {aircraft_context.get(aircraft_type, '')} are not found.")
            continue
        
        # Print the descriptive opening sentence
        print(f"{aircraft_type} {aircraft_context.get(aircraft_type, '')} are:")
        
        # List each service as a bullet point
        for service in aircraft_services:
            print(f"• {service}")
        print()  # Add spacing between sections for readability

Step 3: Test the Function #

Call it with your existing data:

AirCrafts={'Cargo Aircraft':'1','International Aircraft':'2','Domestic Aircraft':'3'}
Services={
 'Cargo Aircraft':[ "Fedx","DHFL","Emirates SkyCargo","Qatar Airways Cargo","Cathay Pacific Cargo" ],
 'International Aircraft':[ "Air India","Air France","BA" ],
 'Domestic Aircraft':[ "TruJet","Indigo","AirAsia" ]
}

SenGen(Services, AirCrafts)

Expected Output: #

Cargo Aircraft that handle international and domestic freight are:
• Fedx
• DHFL
• Emirates SkyCargo
• Qatar Airways Cargo
• Cathay Pacific Cargo

International Aircraft that operate from various airports of India are:
• Air India
• Air France
• BA

Domestic Aircraft which run within India are:
• TruJet
• Indigo
• AirAsia

Key Improvements: #

• Context Injection: Uses the aircraft_context dict to seamlessly add those specific descriptive clauses you wanted.
• Cleaner Logic: Directly maps each aircraft type to its services instead of nested loops that caused confusion.
• Readable Formatting: Adds bullet points and spacing between sections for clarity.
• Error Handling: Gracefully handles cases where an aircraft type has no services listed.

If you want to adjust context phrases or change service formatting (e.g., comma-separated lists instead of bullets), you can easily modify the aircraft_context dict or the service-printing loop.
